REPEATING ATLPAELAT'US Application filed Qctober 25, 192 3.

To aZZ whom iii may concern:

Be it known that l 11 3615 id. DAVEN- Born, a citizen oi the United atesresidii at Camden, in the iounty or Camden a tale of New new and usetulImprovements in Repeating; Apparatus for Talking Machines of which thefollowing is a specification.

One object of my invention is to provide improved apparatus of a durablecharacter which will be etltective after the playing of record toautomatically cause the record to be repeated.

Another object is to so make my improved tus that it can be readilyapplied my; machine and will be adjustable to 1L records of differentsizes. These objects, and other advantageous ends which will bedescribed hereinafter, l. attain in the following; manner referencebeing; had to the accompanying drawings in which Figu e 1 is afragmentary top plan view of inv improved apparatus illustrates in theposition assumes when mounted upon a talking machine, certain of theelements or the talinng machine being illustrate in dot-end-dash linesfigure 2 is an elevation looking in the direction of the arrow Figure 1;certain of the parts being illustrated in section, gure 3 is an enlarged'l ra mentary plan view of certain of the parts shown in Fin;- ures iand 2 parts dotted lines, 7l( A -1.

A bracket 11 is secured to the top 6 of the talking machine cabinet atone side of the turntable 7 and this bracket has an entension 12providing a pivot 13 for a swing- TALKING- MIAQI-HNES.

A, suspension rod 15 isconnectet to the end it; of the be n1 1-5: and has a weight 17 thereonadapted to move the hooked end 18 of the beam "ly under oer operatingconditions. described. The weight 17 may oned within the cabinet and the"he cabinet may be provided with a to permit the rod 15 to extend thetop 6 into the cabinet so that ht will not be exposed to view. A Frame19 has one end pivoted at 20 to bracket 11; said frame having a worm ithereon whic is connected to a friction dish roller .22 adapted tofrirtionally engage the nder surface oi? the turntable 7 as shown in iis the worm 21 will be rotated.

is secured to the shaft 24- and cranli' pin piv tally connected to Thethe link 28 is pivoted at 29 33 which is ally slid gun oway 31 formed inthe top of 11. The rear part of the linlc adjacent the head blorl: 30recess v2 therein. the inner end of which is beveled as shown 33 inFigure e head block 30 has a pin 34 lreely slidthe lower end o? a linltor pitnian 28. upper end oil 1 to a nead blo 7 I q therein the rear endwhich is ad t- ;aged by a plate spring 35 which 0 the head blo'h 30. Thespring 35 has a portion v-rhich extents above the top of the head blocksaid portion being provided with a slot 36 adapted under certainconditions to engage a pin 37 on the beam 1 lhe plate spring normallytents to more the pin 34; toward the link and when the recess isentirely in trout of the pin the forward end of the pin :34 will l movedby the spring; into the recess and this n'iovement of the spring willcause its upper end to move out of engagement with the pin 37 on thebeam 14. A swinging movement of the link 28 on its pivot 29, however,will cause the beveled part 33 to push the pin 34 rearwardly and alsomove spring 35 rearwardly and place it under tension. The top of the ispringxiis preferably bent forwardly as shown at 38 in Figures 2 and 5to permit the pin 37 to flex the top end of the spring 35 forwardly whenthe spring .35 moves upwardly as will hereinafter be described so thatthe pin 37 can enter the slot 36 to assume the position illustrated inFigures 2 and 5.

The friction wheel 22 is held in engagement, with theturntable 7 due tothe connection of a spring 39 which is attached to the frame 19 and to alug 40 on the bracket 11. A latch lever 41 is pivotally connected at 42to the bracket 11 and has a torsion spring 43 adapted to move the lowerarm 44 of the lever-41 intoengagement with the frame 19 under certainconditions and move thefriction roller 22 downward out of engagementwith the turntable 7. The upper arm 45 of the latch lever 41 has a hook46 thereon adapted to engage over a shoulder 47 on a latch 48; saidlatch being pivoted at 49 to the beam 14 and being located adjacent aside surface 50 of the bracket 11. A trip lever 51 is pivoted at 52 tothe bracket 11 and has a shoulder 53 on its lower arm 54 which isadapted under certain conditions to engage over the top 55 of the frame19 at a position remote from its pivot 20. The upperv arm 56 includes asection 57 adjustably pivoted thereto at 58 as shown in Figure 2. Thebeam 14 is adapted to extend under the tone arm and the parts of myinventionare operativeafter the playing of the record to lift the tonearm through the medium of the .beam 14; thebeam 14 slanting so as tocause thetone arm to slide downwardly toward the pivot 13 and then belowered with the reproducing needle in the outer grooves of the record.'Figure 2 shows the parts in the position which they assume just priorto the time in which the reproducing needle will be lowered into theouter. grooves of the record.

A clamping band 59 is secured to the part 60 of the tone arm whichreceives a pivotal movement in a horizontal plane and said clamping band59 has a projection 61 which .is connected to a link 62. The link 62 asmedium of the projection 61and link 62 to push the arm 44 upwardly outof engagement with the frame 19 and thereby permit the friction roller22to again engage the turntable 7. It will be noted that the upper :arm'56of the trip lever 51 is offset so that the weight of the'upper armnormally tends to move the lower arm 54 to cause the shoulder 53 to moveover the top 55 of the frame lever 41.

Considering that the crank pin 27 is moving downwardly, as shown inFigure 2, to move the beam 14 downwardly due to the connection between"the link 28, head block 30, spring 35 and pin 37, the tone arm, havingbeen previously swung to its outermost position, will be lowered topresent the needle t0 the outer grooves of the record. When the crankpin 27 reaches its lowermost position the hook 46 of the latch lever 41will be moved over the shoulder 47 of the latch 48 and the arm of thelatch lever will move down into engagement with the frame 19 and swingthe frame 19 against the action of the spring 39 to move the frictionroller 22 down out of engagement with the turntable 7. The section 57 ofthe trip lever 51 being free of the tone arm will allow the shoulder 53of the arm 54 to move overthe top 55 of the frame 19 and thereby preventthe frame 19 from moving upwardly until the tone arm again strikes thesection 57 which will not occur until the nextrepeating action.

After the record has been completely played, the end 66 of the trip arm63 will have been actuated so as to inove the adjusting screw 67 intoengagement with the arm 44 of the latch lever 41 and the latch leverwill then be swung against the action of the spring 43 to pull thehooked end 46 out of engagement with the shoulder of the latch 48 and tomove the end 44 of the lever 41 away from the frame 19. The pin 34having previously moved into the recess32 so as to free the pin 37 ofvthe spring 35, the counterweight 17 will sn ing the beam 14 on the pivot13 and will lift the sound box out of engagement with the record and,due to the slant of the beam 14, the tone arm will slide downwardlythereon until it engages and moves the section 57 of the trip lever 51and will then move the shoulder 53 away from the top of the frame 19.The frame then being released will be moved by the spring 39 to causethe friction roller 22 to again engage the turntable and thereby actuatethe worm 21 to turn the crank and to thereby effect the movement of thehead block 30 and spring upwardly so to'cause the pin 37 to engagethrough the slot 36 as previously described and a continued movement ofthe crank will cause the beam 14 to be moved downwardly having beencaughtby the spring 35 and the sound-box will be lowered so as to causeits reproducing needle to again engage the outer grooves of the recordto repeat the playingof. the same.

turning theadjusting screw 67, the timing of the releaseof the latchlever can be varied to suit different requirements as to the size of theplaying portion of a record,

1,444,171 are and the section 57 of the trip lever 51 can also be swunginto various positions so as to vary the position at which the releaseof the frame 19 by the arm 54 will be accomplished.
